This book gives many names and years of French patents. They wanted to classify them, perhaps as American patents were classified, so as to make the French works useful to American inventors or to identify previous practice more effectively.

In some cases, in which we have English-language summary titles from this source, with or without an "original title", I have used quotation marks, thusly as "...*", in accordance with a protocol within this publication.
